We've known for over a week that Kanye and adidas would be launching the YEEZY Powerphase "Core Black" on March 17th, but today sees the Three Stripes making it official. Retailing for $120, the all-black kicks feature a soft leather upper mounted atop a die-cut EVA midsole and a high-abrasion rubber outsole underfoot. Gold foil CALABASAS branding on the quarter panel completes the look. Check out detailed images in the gallery below, and expect the YEEZY Powerphase "Core Black" to be available through YEEZY SUPPLY, adidas.com/YEEZY and select adidas retailers. Additionally, sign ups for the adidas Confirmed app are open now through noon ET on Wednesday, March 14, with participating cities including Chicago, Los Angeles, Miami, New York City, and San Francisco.
